OEE measurement is also commonly used as a Key Performance Indicator (KPI) in conjunction with lean manufacturing efforts to provide an indicator of success. It quantifies how well a manufacturing unit performs relative to its designed capacity, during the periods when it is scheduled to run. It is a well known concept in maintenance and is a way of measuring the effectiveness of a machine whic...

The wide ecological area consists of a rangeland with special vegetation and one of the key factors in rangeland management is to select Management Indicator Species (MIS). Management indicator species based on a new method such as Analytical Network Process-Decision Making Trial and Evaluation (ANP-DEMATEL) is one of the most important stages in the successful Range management as choosing a su...

In this paper, we propose an efficient and secure key establishment protocol that is tailored for Wireless Mesh Networks. The protocol is based on identitybased key establishment, but without the utilization of a trusted authority for private key generation. Instead, this task is performed by the collaboration of mesh nodes; a number of users exceeding a certain threshold form a coalition to ge...

This paper presents alternative security methods based on DNA. From the alternative security methods available, a DNA algorithm was implemented using symmetric coding in BioJava and MatLab. As results, a comparison has been made between the performances of different standard symmetrical algorithms using dedicated applications. In addition to this, we also present an asymmetric key generation an...

The classical certificate systems are computationally inefficient, since they use signature operations based on public key cryptosystems. The nested certificates (A. Levi, Design and performance evaluation of the nested certification scheme and its applications in public key infrastructures, Ph.D. Thesis, Department of Computer Engineering, Boğaziçi University, Istanbul, Turkey) are proposed to...

Due to the resource constraints on sensor networks, many recent key management schemes exploit the location of nodes in order to establish pairwise keys. Despite these efforts, location discovery for sensor networks is very difficult, because existing schemes have failed to consider changes in the signal range and the deployment error. As a result, network performance may accidentally decrease,...

Vaccination considered as one of the most cost-effective health interventions worldwide  through prevention and control of many serious childhood diseases (1). It is estimated  global coverage of  Dose 3 of Diphtheria, Tetanus, and Pertussis (DTP3)among children one year old has been 86% in 2014 (by range from 77% to 96%  in African Region and Western Pacific Region; respectively) (2). Globally...

The integration of low level management functionalities provided by TOSCA and high level processes as defined by ITIL may provide significant improvement opportunities to the application provider as on both levels workflow technology can be employed. In this paper, we present Key Performance Indicator Analysis Plans as first idea how both approaches can be integrated.

When comparing the average citation impact of research groups, universities and countries, field normalisation reduces the influence of discipline and time. Confidence intervals for these indicators can help with attempts to infer whether differences between sets of publications are due to chance factors. Although both bootstrapping and formulae have been proposed for these, their accuracy is u...
